My account disabled for over limit , but all forms missing

My account disabled for over limit , but all forms missing

How can i clear space if i can access  the form ???

Please replace form so I can delete files no longer required

<script type="text/javascript" src="//form.jotform.us/jsform/30277662283154"></script>

And i will immediately clear space to meet quota

I've answered to you here: http://www.jotform.com/answers/411925

Also, when an account goes overlimit, it's disabled, along with other forms.
